Upon shaft 6, is pivoted the rocker-arm 10, which has secured upon its forward end the plate or bracket 11, upon which the head-light .12, is detachably secured in the usual way; while the rear end of said rocker-arm 10, is formed with the T-hcad arm 13, which is formed with a double curve; the two ends havin the downward curve, as shown in Fig. 6, and the forward curve, as shown in Fig. 4. Directly under said curved head 13, and in con tact with the under side thereof is secured by a stud plate 14, to the front of the car 1, the roller 15, upon which the head 13, is designed to slide; while for retaining the head 13,- in contact with said roller 15, and to balance the weight of the head-light, I provide the spring 16, which has an end secured to said T-head arm 13, and the other end to the shaft 6.

The operation of the device is as follows: As the car reaches a forward truck is turned to one side or the other; and by the action of the rods 9, which will turn the cross-arm lun a, in the county of Lancaster'and State of ennsylvania, have invented certain new and useful Improvements in Automatic Headlight-Adjusters, of which the following is a specification,'reference being had therein to the accompanying drawing.

My invention relates to improvements for automatically operating head -lights for street cars andother v'e icl'es.

The objects "of the invention are to pronew and novel support at'tached'to the car In V as the direction of the vethe head-light will be shifted to either side of a center line in such a mansame time that the li ht is moved in a horizontal manner, it is a so automatically moved the light will be deflected downwardto fully illuminate the short road-bed, and at greater curves thelight will be raised in proportion to the curve to cast its-rays at a greater distance from the vehicle.

With these and other objects in view my combination of parts as will hereinafter be fully described and claimed in the annexed specification and illustrated in 'the accompanying drawings forming a part ofv the same, and in which like figures pf reference onding parts in all of the but it is ully understood that while I have here described my invention as herewith illustrated, I do not confine myself to the exact design as shown, as slight changes may be made withimthe scope of the alp .the invention.
